PRINTING-PRESS.

SPECIFICATION forming part of Letters Patent No. 547,758, dated October8, 1895.

Application filed October 16, 1893. Serial No. 488,235. (No model.)

To aZZ whom, it may cancer-n.-

Be it known that I, SEMER G. WVELLS, a citizen of the United States ofAmerica, residing at Des Moines, in the county of Polk and State ofIowa, have invented a Printing-Press, of which the following is aspecifioation.

My object is, first, to rotate a flat bed carrying a type-form in such amanner that it will engageaplaten at each revolution as required toprint an impression upon paper from the form; second, to carry androtate two or moro flat beds carrying an equal number of typeformssimultaneously in such a manner that they will be successively engagedby the' platen at each revolution of each form; third, to combine anindependent inking device with each flat bed in such a manner that eachform on each bed may be inked with a color differing from the colorsapplied to the other forms, as required in chromatic printing, or eachform inked independently with colors alike; fourth, to combinepaper-feeding mechanism with the rotating bed-carrier and the platen insuch a manner that paper from a roll will be advanced between the platenand each form as required to print an impression by means of each formwithout requiring any intermittent motions of the rotary bed-carrier;fifth, to combine paper-cutting mechanism with the rotary bed-carrierand the paperfeeding mechanism in such a manner that it can be adjustedto cut oifpaper from a continuous roll or from fiat paper after eachimpression of the form or forms carried on each flat bed, or after anynumber of impressions have been made by different forms on difierentbeds during each revolution of the rotatiug bed-earlier; sixth, tocombine paper-cutting disks with the paper-feeding mechanism in such amanner that the roll-paper can be divided longitudinally and trimmed tosuit the sizes of forms carried on the fiat beds; Seventh, to combine afeed-board with the paper-feeding and paper-cutting mechanism in such amanner that flat cut paper can be substituted for roll-paper in theoperation of my invention; eighth, to provide mechanism for controllingthe Operations of the paper-feeding mechanism in such a manner that thepaper is retained stationary relative to the platen as required to makeimpressions thereon successively from different forms on different bedson the rotary bed-carrier; ninth, to combine stop mechanism with thepaper feeding and cutting mechanisms in such a manner that the motion ofthe paper can be arrested, so that different lengths can be advancedsuccessively as required to suit forms of difierent sizes upon thedifferent beds carried by the rotary bed-carrier.

My invention consists in the construction, arrangement, and combinationof a rotatable bed-carrier, flat beds adapted to support forms of typein position as they are carried around in a circle, inking mechanisms,paper-cutting mechanism for cutting od different lengths from a roll ora flat sheet, mechanism for dividing paper longitudinally, stopmechanism for regulating the lengths of paper cut off from a roll or a.flat sheet, and driving mechanism with a supporting-frame, ashereinafter set forth, pointed out in my claims, and

illustrated in the accompanying drawings, in

which- Figure 1 is a right-hand elevation of my press, showing the formof the end portion of the frame, which has a circular openingin thecenter, vand the edge of the circular opening broken away at one pointto disclose the relative position of the toothed cirpular end of thebed-carrier fitted in the circular opening of the frame. One of the armsformed integral with the frame to support the axis of the rotatiugbed-Carrier is also partly broken away. Part of the top portion of theframe, where the cutting mechanism is located, is also broken away todisclose disk-cutters for splitting and trimming paper. Fig. 2 is a-noutside elevation of a portion of the left end'of the frame having acentral circular opening corresponding with the opening in the righthandelevation shown in Fig. 1. The end of the rotating bed-carrier shownwithin the circular opening has a concentric groove in its face, withinwhich a pin is adjustably fastened to engage and operate thepaper-cutting mechanism, also shown in this view.

Fig. 28 is anenlarged 'Sectional view showing the connection between the drive-shaftand the rotating bed-Carrier. Fig. 29 is a sectional view of afeed-board connectedwith the frame in place of a roller for supportingpaper. Fig. 30 is an enlarged detail view showing the arrangement oftapes and rollers for carrying the paper between the platen andtype-forms on the beds. Fig. 31 is an enlarged sectional view of Fig. 9,showing two wheels connected on a hollow hub.

The letter A, Wherever shown in the various figures, designates an endpiece of the main frame, and A2 are cross-pieces that connect the twomating end pieces A.

A3 are the arms formed on or fixed to the outside faces of the endpieces A to support bearings for the axis of the rotating bed-carrier ina concentric position with the circular openings in the central portionsof the pieces A.

A4 are the circular end pieces of the rotating type-bed carrier fittedin the circular openings of the end pieces A. V

A5 is the annular groove in the outside face of one of the pieces A4,-asclearly shown in Figs. 1 and 26, to admit the fastening devices of thetransformable cam-wheel A6. It is obvious that the piece A4 is thus madeto serve as a base upon which to fix the cam-wheel A6 in such a mannerthat the sections thereof can be detachably and interchangeablyfastened, as required to transform the cam-surface on its'periphery, byincreasing and diminishing the lengths of spaces between the inclinesthat govern the operation of the paperfeeding mechanism, so thatdifferent lengths of paper can be advanced at different times to suittype-forms difiering in size.

Figs. 19 to 26, inclusive, illustrate the con- IOO struction andapplication of the interchangeable sections composing the transformablecam-wheel A6. It is obvious that the width and length and shapes attheir outerends vary as required to produce a wheel that has a variablecam-surface on its periphery. All the sections excepting one,zNo. 25,are provided with a fixed stud adapted to enter and traverse the grooveA5, as shown in Fig. 26, to be collectively keyed fast by means of asection that is provided With a bolt, ,as shown Fig. 25. In order tofasten all the sections securely, one of them is provided with adetachable bolt A7, that has a head adapted to be turned in the grooveA5, and the section then placed upon the bolt and secured in its placeby means of a nut, as shown in Fig. 25.

A8 is the axle of the rotating bed-carrier to which the endpieces A4 arefixed.

A9 is the driving-shaft shown in Figs. 4, 8, and 28.

One of theend pieces A4 has cpgs on its periphery and is engaged by agear-wheel B on the drive-shaft A9, as required to be rotated thereby.

B2 is a fiat platen that has projections B3 on its ends adapted to slidein bearings B4, formed in the end piecesAon the frame, as shown in Fig.5.

Eli is a gear-.wheel that meehes with the drive-wheel B and transmiteVmotion to the zoV platen in its bearings B4 by means of cranks ll,formed in the shaft B7, to which the gearwheel B5 is fixed.

B8 are bridles projecting upward from the ends of the platen throughwhich the crankpins ll'J are extended from the arms B6, as clearly shownin Fig. 7, in such a manner that a rectilincar reciprocating motion willbe iinparted to the platen at each revolution of the .sli-att 137 as thegang of bedsV carried by the bed-carrier are successively brought inposition to present type-forms against the platen, as shown in Fig. 5,and as required to print an impression upon paper between the typeferiuand the plaften. The type-form on the bed and the platen move in thesame direction and at the same rate of speed at the instant theimpression is made and during suf` ficient time before. and after theimpression to allow the parts to clear and prevent slurring, the platenmoving in astraight line and the type and bed in a circle, and it istherefore obvious that the impression is made when the centers of themoving platen and the moving type-bed are inline with the axis Aof thebed-carrier and the axis of the shaft B7 that operates the platen.

O is a device for throwing the paper-feeding mechanism in and out ofgear at intervals by means of the transformable cam-wheel A5. It is oftriangular form, as shown in Fig. 1, and supported in a hearing O2,fi'xed to the face of the frame-'piece A in such a manner that anantifriction-'roller at its bottom will rest upon the periphery of thewheel and rise and fall upon the variable cams.

Cais a duplex rackthat has a slding connection with'the top edge of thedevice O.

O4 is a bar thathas a vertically-sliding connectionuwith the end of rackCSi and a bridle C5 at its other end, through which is extended acrank-pin C6 from the face of a disk C7, fixed to the shaft B7. As thedisk C7 is rotated the rack Ca will be reciprocated, andwhen it engagesthe pinion C8 motion Iwill thereby be imparted to the feed-roller C9,(shown in Fig.

- 5,) as required to actuate the paper-roller 01 contiguous thereto,between which two rollers paper is advanced to the type-forms on thebeds as they are brought into position relative to the 'platen.

D is a roller located on the delivery side of the press and connectedwith the roller C9 by means of an endless tape D4, and D2 and Ds areguide-rollers that direct the tape.

D5 is a roller connected with the roller (11 by means of 'a tape D6, andD7 andB are directing-rollers that engage the tape D.

D represents a roll of paper and D1o (shown in Fig. 29) a feed-board.Paper advanced from the paper-roll or the said feed-board passes betweenAhe rol-lers C9 and CH and the carrying tapes D4 and D6, and by means ofsaid tapes the paper is carriedaad guided between the platen andtype-form, where it receives an impression, and then onward to andbetween the rollers D' and D5.

F is a roller carryingcutting-disks, and F' is a mating roller, and asthe paper is advanced from between the rollers D and D5 and between Fand F' it is split -longitudinally into widths as desired.

F2 (shown in Fig. 2), is a belt connected with a pulley Faon the end ofthe shaft B7 and the roller F', as required to actuate thepapersplitting rollers F and Fp'. v

F4 is a knife and F5 a knife-carrier fnd FG a shear-edge, and as thepaper passes between the cutters F and F' and is split and trimmed thedesired widths it is advanced past the shear-edge F6 and cut the desiredlengths by the descent of the knife F4.

F7 is a lever pivoted to the frame-piece A and connected with theknife-carrier yF5 by means of a bent bar F8 or in any suitable way, sothat the knife will be actuated by the vibration of the lever F'l, asrequired to cut off the length of paper desired to fall upon thereceiving-table F9.

' H is a spring that in its normal position retains the knife F4elevated.

H' is a groove in the face of the left-hand end piece A4, and H2 is apin adjustably clamped fast in said-groove, as shown in Fig. 3, toengage the free end of the lever F7, as required to vibrate the saidlever. It is obvious any number of pins may be thus attached tosuccessively engage and vibrate the said lever as the bed-carrier isrotated, and as required to cut off dierent lengths of paper atdifferent intervals.

113 is an inclined groove that extends in- Ward from the edge of thecircular end piece A4 and intersects the groove H' in such` a mannerthat the heads of pins Hgcan be readily passed from the outside of thepiece A4 into the groove l-I', and vice versa.

It is obvious from above description that as the gear-wheel B, whichmeshes with the end piece A4, having cogs on its periphery, is rotatedthe bed-carrieris rotated and the gang of beds carried thereby aresuccessively brought in contact with the platen B2. It is also obviousthat one or more beds may be carried by the bed-carrier,or when morethan one is carried one or more of them may be carried empty while oneor more carry typeforms. It is also obvious that the ratio ofrevolutions of the shaft B7 and the shaft A8 must be in the proportionof one to the total number of type-beds carried.

J are the flat beds for carrying type-forms, connected with thebed-carriers in such a manner that they will move in the same orbit andsuccessively pass the platen B2, as required to make an impression uponthe`paper as it passes the platen B2.

J' (shown in Fig. 5) is a pivot in the end of the bed J, connected withthe bed-carrier A4.

J2 is a chase carried on the bed J as shown in Figs. 5 and 10, asrequired to retain the type-form Ja, as shown in Fig. 5.

J 4 are sprocket-wheels.

J 5 is a plate of segmental shape 'provided [IOV l-hl

with a fiange at its top, as shown in Figs. O, 10, and 17; Jii, aspring. (Shown iu Figs. 9, 17 and 115;.)

.17 and .'JS are integral pinions, and Ji' is a roller, all assembled ona shaft J, that is fixed to the type-bed J, as shown in Figs. l, 9, and17.

The sprocket-wheels J* have lamber-faces K, and the hubs of the integralpinions J7and J have corresponding ratchet-faces K' to engage theratchet-faces K of the sprocket-wheels J* and serve asaclutch by meansof which motion imparted at intervals from the pinions .17 and .lE tothe sprocket-Wheels J'l. The spring Jf' is placed on the hub of thepinions JT and JH, which extends through the plate J5 and rests againstthe face of the pinion .17, as shown in Fig. 17, in such a manner thatit will hold said pinions disengaged from the sprocket-wheels Jet.

K2 is an endless chain extended over the sprocket-wheels J4, as shown inFigs. 4, 5, and lt).

K5 are composition inking-rollers journaled to the chains K2 in anysuitable way, in such a manner that they will be supported and carriedthereby, as required to traverse the typeforms on the beds J.

K4 and K5 are metal rollers journaled to the metal plates J5, to becarried therewlth.

K5 is a composition roller that engages the surface of the roller K5. Itis journaled to brackets K7, as shown in Figs. yi, 9, and 10.

K8 is a cam-groove on the end ofthe roller K4, as shown in Fig. 13, andK is an arm placed on the said grooved journal, as shown in Fig. fl, insuch a manner that the arm will move back and forth on said journal asthe roller is rotated. This movement of the arm is caused by the pin K1,fixed in the arm to extend into the cam-groove, as clearly shown in Fig.l-lz. The shaft of the roller K5 is extended through the brackets K7 andthrough the movable arm K and secured thereto by means of collars, or inany suitable way, so that the motions of the arm will carry the rollerback and forth endwise.

L are spring-actuated levers pivoted to the plate J5 by means of a rodL2 to carry a composition roller L5 'tt their` inner ends in such amanner that the roller Will, in its normal condition, be in engagementwith the roller K4, as shown in Figs. lO, and 12.

L1 is a curved sheet-metal plate extended between the levei-s and hingedat its top edge to the rod IF.

1.5 are end pieces of the plate L* that adapt it to retain printerisink.

1.5 is an eccentric roller journaled to the plates .15 in such a mannerand position relative to the plate L4 that it will retain the free edgeof the plate in contact with the roller K5, as shown in Fig. IO.

It is obvious that the flow of ink from the plate 1;* to the roller K5can be readily regulated by simply turning the eccentrie roller.

LT is a gear-Wheel journaled on the end of tne roller K5, that extendsthrough the-plate J5 and is located on the inside of said plate. If is acorresponding wheel on the outside of the plate J5 and fixed to thewheel L7, so that they will rotate jointly ou the shaft of the rollerK5.

It is obvious that the bored hub of one of the wheels is extendedthrough a bearing in plate J5 and the other wheel then fixed to theextended hub and the shaft of the roller K5 extended through the samehub to rotate therein.

L is a gear-wheel fixed to the roller K1 and meshes with and is actuatedby the gear Li.

M is a pin-wheel fixed on the opposite end of the roller K5 from thegear-wheel L7.

M2 is a pin projecting from the face of the frame A, as shown in Fig. 5,and actuates the pin-wheel every time a bed J and the plates J5 arecarried past the pin, as required to impart motion to the roller K5.

M3 (shown in Fig 5) is a cam fixed to the frame A in such a manner thatit will engage and actuate the lever L .every time the lever is-broughtin contact therewith, as required to depress the roller L3 to bring itin contact with the roller K5 to take ink therefrom and to be rotatedthereby at the same time the roller K5 is being actuated by the pinwheelM, passing over the pin M.

N are concave racks fixed to the inside face of the frame A, as shown inFig. 5 and indicated in Fig. 8.

K5 are convex racks fixed to the end piece A4 of the rotatingbed-Carrier, as shown in Figs. 5 and 6. As the bed-carrier is rotated,the wheels .15 engage the concave racks N and the wheels JT the convexracks N2,successively, and are actuated by said racks, as required tooperate the sprocket-wheels J4 to carry the inking-rollers K3 around thebed J, and at the same time to retain the bed in a parallel positionrelative to the platen D2.

Figs. 1 and 5 are drawn ou a scale of onefourth (l) inch to the inch.The disk CT is four and a half (4%) inches in diameter. pin (J6 is ahalf (fl) inch in diameter. The slot in the bridle C5 is four (4) inchesin diameter. This gives the pin C6 a motion of three inches and a half(3%) in the bridle C5, both going and coming, which is equal to themotion given to the platen B2 (see Fig. 5) by the cran kpin BT, workingon the arm B5, and the pin B9, working in the bridle B5, which are allof the same relative proportions to each other. A motion of three and ahalf (3%) inches is rimparted to the platen B2 and to the rack C3, bothgoing and coming, making a total motion of seven (7) inches to eachimpression when all the beds are carrying forms. Therefore it is obviousthat the extreme limit of paper that can be used on a form When there isa form ou each bed is seven (7) inches, or when there is a form on everyalternate bed fourteen (14) inches of paper can be used, and when thereare two forms on two successive beds one form can use seven (7) inchesof paper and The.

Awheel A6 nearest its axis.

the other one twcnty-one (21) inches, or each form can be printed on theextreme ends of a sheet tWenty-eight (28) inches long, o'r by cutting intwo can be made into 'two (2) jobs of fourteen (t4) inches length, orcan be` printed in the middle of a job twenty-eight (28) inches long.\Vhen each alternate form is used each form can be given fourteen (t4)inches of paper, or a job can be printed twenty-eight inches long witheach alternate page blank, or when forms are carried on all the beds,not duplicates of each other, a job may be printed twenty-eight (28)inches long, or of four (t) pages each seven (7) inches long. This showsthe extreme length of paper that can be used in any job in the pressherein described, and so the problem now arises how to get that lengthof that paper through the press at the proper speed so as not to slur outhe type or to tear the paper.

The toothed rack C3, attached to the slidingbar C4 and connected to thebridle C5, is driven by the crank-pin C6 at the same rate of speed asthe platen B, as above described. The pinion Os on the shaft C9 in Fig.1, has a diameter of one (l) inch -on its pitch-line. The roller on theshaft C9 and the roller Cm, Fig. 5, which co-operates with C9, are oneinch in diameter and should be made scant enough so that when the tapeis over them they will have the capacity of an inch-roller in movingpaper. Each side of the toothed rackC3 is toothed for a distance ofIfour (4) inches. VVhen the device O is in the position shown in'Fig. 1the feed mechanism is inactive and the paper standing still. When themachine is started the bed-carrier rolls around until theantifriction-roller which carries the device O drops down to theperiphery of the cam- If the different parts were so' assembled on theirvarious shafts that the platen B2 and type-form were now in conjunclionand the rack C3 was in such a position that the pinion Oe was clear atone end of the rack C3, and assuming that we Want to print paper seven(7) inches to each form and a form on each type-bed, the cam-wheel A6must be so constructed that the antifi'iction-roller which carries thedevice O will remain on the inner periphery until the disk CAT, carryingthe pin C6, has made half a revolution and carried the rack C3 until thepinion reaches the opposite end of the rack. At this point the saidantifriction-roller must be elevated to the periphery of the cam-wheelA8 most distant from the axis of said wheel, and then the press isconjunction with and at the time it is going away from the platen it ismoving With the platen, so that there is no friction between the paperand the platen, and the platen and type-bed are moving together and allthe parts working harmoniously without friction between the type and thepaper or between the paper and the platen. Now, when it is desired touse less than seven 7) inches of paper, the cam-wheel A7 must betransformed so as to increase the length of time between the racks C3going out of mesh on one side and in the mesh of the other side of thepinion CS. v time while the motion of the platen is being reversed, andmay be increased down to a time when there is danger of slurring by thepaper standing' still while the type-bed is near the platen.

It is obvious that at each revolution of the bed-carrier each bed willbe carried around in the orbit of the oarrier without changing itsparallel position relative to the platen, and that this is accomplishedby means of the concave racks N, fixed to the statiouary frame of thepress, and the smaller convex racks N2, fixed to the rotating carrier,and the gearwheels JB that travel in the concave racks N and thegear-wheels J 7 that travel on the smaller convex racks N2.

Referring to Fig. 8, which represents the pitch-lines and the orbitstraveled by the various moving parts when the center of a bed is at thepoint marked a, the two gears J8 are in mesh with the racks N and thegear-wheels .17 are in mesh with the racks N2, the gear-wheels 'J7 onthe right-hand side of the bed just going out of mesh and the gears .17on the left-hand side just going into mesh with the rack N,

-and as the bed-carrier moves forwardV for a short distance the gears onthe left-hand side of the bed are both in mesh, JB with rack N and J7with rack NZ. When the left-hand gearsget to the point b, J8 runs out ofmesh. From thepoint b to the point c, J8 is in mesh with rack N on theright-hand side of thebed and .17 is in mesh with rack N2 on thelefthand side ot' the bed. The said racks and pinions are soproportioned that the pinions at the opposite ends of the beds will havethe same rate of rotation. From c back to the point a the movementsdescribed are simply repeated, the work done by the left-hand gearscoming from ato c now being done by the right-hand gears going from c toa. In other words, the right and left hand gears act alternatelyrelative to the racks N and N2 during each revolution ot' thebed-carrier. v

\Vhile thegroove P2 is concentric With the axes of the beds it isobvious that they simply act as a. clearance for the rollers whichtravel i-n the grooves P and P2; but. when said rollers are inithegroove P which is u`ot concentric with the axes of the beds the Thisholds the paper still for a longer IOO llO

grooveP guides said rollers and maintains the beds in their horizontalpositions during the entire revolution of the beds except at the pointwhere all the axes of the gears J7 JS, the journals J', and the axis ofthe bedcarrier A8 are all in line. At this time the gears J7 and J8 aretied together by the sprocket-chains and both running in the samedirection and same speed, being driven by the racks N and N2, bothsidesV of the bed being carried forward at the same time and same rateof speed. Neither side of the bed can lag behind or get ahead withoutbreaking the sprocket-chains, and as this forward motion is equal to theforward motion given to the bed by the bed-carrier`it is obvious thatthe type-bed cannot tip, for the reason that it is supported at threepoints-first, the journals J', to which power is applied by thebed-Carrier; second,by the gear J8 on one side, and, third, by the gear.JT on the other side.

1) are grooves in the inside face ot' the frame-piece A correspondingwith the segment of the orbit of the gears J7and JS; which is outside ofthe boundary line of the end piece A4 of the bed-carrier.

P2 are grooves in the surface of the inside face of the end piece A4 of.the bed-carrier, and together with the motion of said bedcarriercompletes the orbit traveled by the gears J7and JS. The rollers .19 onthe ends of the shafts J10 traverse the grooves P and P2 successivelyand serve as guides and bearings for the gears JT and JS. When a typebedJ is at or near the points marked a and c in Fig. 8, the rollersJ9,traveling in the grooves P and P2, are suficient guides and supportfor the type-bed to keep it in its parallel position relative to theplaten B2, and the gears J7 and JS are disconnected with thesprocket-Wheel J4 by the action of the spring Jfi, and thesprocket-chain K2 and the rollers K3 are at rest, said rollers K3 beingin contact with the metal roller K4 and being actuated thereby, as shownin Fgs. 5 and 10.

The gear-wheel L8 mesheswith and is actuated by the convex rack N2 andruns loosely upon the shaft of the roller K5, connecting with anddriving the gear L7, which meshes with and actuates the gear L9 anddrives the roller K4, thereby transmitting ink from the receptacle L4 tothe form-rollers K3 while at rest, as heretofore described,` and asshown in Figs. 4, 9, and 10. After the inipression is o made by thetype-forms carried upon the bed J coming in contact with the platen B2and the type-bed is advanced by the rotary motion of the end piece A4 tothe end of lugs R and R2 (Which are projections on the faces, theframepiece A, and the end piece A4 of the bed-earrier, one set beingshown in Fig. 5 and a corresponding set is provided on the oppositeside) the ratchet-faces of the gears J7andl that means the bed is heldin its parallel position relative to the platen J. The gears" then runoff the lugs R and R2 and the sprockets, chaius, and form-rollers cometo rest until the type-bed is carried to the opposite side of the frame,where corresponding lugs are reached and the gears thereby again lockedto the Chains, as before stated, and the form-rollers carried over theremaining half of their trip. After passing off these lugs, the rollers,having finished their trip, come to rest again, as before described, incontact with the inking-roller K4. The type-form vthen passes inconjunction with the platen, 4as heretofore described.

It is obvious that as each bed and type form thereon has acomplete setof rollers and inking apparatus each form may be inked with a differentcolor of ink. It is also obvious that as many colors may be printed upona sheet as there are type-beds carried by the rotary bed-Carrier byadjusting the transformable cam-wheel so that the paper will be held ina stationary position relative to the platen until the desired numberofcolors have been successively printed thereon.

If it is desired to print from colors, put a different color in each oneof the four fountains, adjust the transformable cam-wheel so that thedistance the paper will be advanced by the periphery nearest the axis ofthe bedcarrier plus the distance it will be advanced by the peripheryfarthest from the axis is.

equal to the size of the job required. This fixes the matter so far asthe first form is concerned,and the balance of-that quarter of thecam-wheel should be filled with the sections making the middle-sizedperiphery for holding the feeding mechanism inactive. The other threequarters of the cam-wheelmust now be const'ructed so that the paper willbe drawn back after each iinpression far enough to be ready to becarried forward with the bed and platen in making the succeedingimpression.

S (shown in Fig. 29) represents a device for holding cut paper on thefeed-board.
